Once I fixed the line breaks, the table made sense. The 2SB902, 2SB1053, KT3107G, KT639E, 2SB736, BT404, CPH6520, FC139, FC149, kT216A, KT218x, MMBT404, and 2N5373 are obsolete, 2SB1189, 2N6730, has BVcbo = 5V The 2SB1693 is a find, BVcbo = 15V, in stock but also now obsolete. So that DB is pretty badly out of date, it looks like.

There are a number of ways to reverse Veb stress, the most common of which is to simple add input and shunt resistors that do not grossly affect forward operation. Another is to add a diode. Component limitations are one of the things that make design more interesting than jigsaw puzzles. You don't just sit arround, waiting for the right parts to become available, but it helps to know what is... RL

There are lots of prebiased ('digital') transistors that'll do that in one package. In the present case I just added a BAV99W to the PNP side. Thanks again Phil Hobbs

Like I said, I suspect many BJTs can handle the voltage, without saying so. At any rate, I don't think Central Semi is one of those NXP-like companies that go around axing slow-moving or out-of-favor parts. And it's not likely Mouser would keep so many in stock, if it wasn't moving. Also, at 23 cents ea in reels, a lifetime supply isn't a deal breaker. -- Thanks, - Win

But for customer designs and licensing, that doesn't fly so well. Cheers Phil Hobbs

I doesn't mean they're dead dead -- more like an expensive legacy zombie state. The price jacks up many times, depending on demand I'm sure. 2N2222A, 2N2369, 2N3866 and many others are still in production -- but sit down before you buy a box of them. :^) Make of that what you will. Forever available? Possible; certainly more likely than other sources. Commodity pricing? No way Jose.
